  1. What is the purpose of checking the slack adjusters during a pre-trip inspection?

    Answer: To ensure brakes are properly adjusted so they apply evenly

    Checking slack adjusters ensures each brake is adjusted properly so all brakes apply with equal force, preventing pulling or uneven stopping.

  2. When inspecting the fuel system during a pre-trip, what are you looking for around the fuel tanks?

    Answer: Leaks, secure mounting, and properly capped tanks

    You visually check for fuel leaks, verify tanks are securely mounted, and confirm filler caps are tight to prevent spills or fires.

  3. During a pre-trip inspection of the lighting system, which lights must be functional for daytime operation?

    Answer: All lights including clearance and marker lights

    All required lights — including clearance lights, marker lights, turn signals, brake lights, and headlights — must function properly at all times.

  4. What does it indicate if the air pressure in the brake system drops more than 3 psi per minute during a static leak test?

    Answer: There is a leak in the air system that must be repaired

    A drop of more than 3 psi per minute in a single-vehicle system (or 4 psi in a combination) indicates an unacceptable air leak requiring repair.

  5. When inspecting wheels and rims during a pre-trip, what are you looking for on the lug nuts?

    Answer: Rust streaks, missing nuts, or cracks around the bolt holes

    Rust streaks can indicate loose lug nuts rubbing against the wheel, while missing nuts or cracks are direct safety defects.

  6. Why is it important to check the header board on a flatbed trailer during a pre-trip inspection?

    Answer: It prevents cargo from sliding forward into the cab during hard braking

    The header board (headache rack) protects the cab from cargo shifting forward under hard braking or in a collision.

  7. When inspecting the rear of a trailer during a pre-trip, what should you verify about the ICC bumper (rear impact guard)?

    Answer: It is not bent, cracked, or missing

    The rear impact guard must be structurally sound with no bending, cracks, or missing components to protect against underride crashes.
